Just throwing in a thought.
The holder door is spring loaded and opens when a solenoid clicks the release.
That give 3 areas to look at:
The solenoid - is it crook?
The holder door/flap - Is there a bit of last weeks breakie stuck in the hinge :grin:
Spring stuffed - broken or dislodged, not allowing the flap/door to 'spring open'
Take a reel of number 8 'n she'll be right mate :grin:
Joking aside, I hope that you get it sorted.
